Visa for Taiwan

Just heard that it can be extremely hard to get a visa to Taiwan, don't know if it is true or not, just want to cite what I heard:

" yeah it can be really hard to go to taiwan now, you can not go unless you know someone in taiwan and he/she can garantee you that you are not spying in taiwan, unless they are sure you are not a spy, otherwise you can't go....you know they wouldn't give the panda from Chinese mainland a visa cuz the panda don't know anyone in taiwan who can garantee it not spying there..."

This is fucking ridiculous, but yeah it happens...
